RISStability and Deformation Analysis for Geotechnical Problems with Nonassociated Plasticity Based on Second-Order Cone Programming
Publisher: American Society of Civil Engineers
Abstract: The second-order cone programming (SOCP) optimized FEM (named FEM-SOCP) is extended to solve the geotechnical problems involving nonassociated plasticity. When FEM-SOCP is used with strength reduction, FEM-SOCP generally ...
Geotechnical Strain Localization Analysis Based on Micropolar Continuum Theory Considering Evolution of Internal Characteristic Length
Publisher: ASCE
Abstract: Within the framework of second-order cone programming optimized micropolar continuum finite-element method (CosFEM-SOCP), the geotechnical strain localization can be adequately modeled. In most existing literatures, however, ...
